a dry (test) run of the cutting operation to
check that there are no problems and 
everything is correctly adjusted.

NOTE: 

Before performing a cut, ensure the 

blade is at full speed. Failure to do this will 
cause your blade to become blunt and 
cause the blade to lock-up.

7. Turn on the Mitre Saw, wait for the blade 
to reach full speed and then lower the 
cutting head whilst pushing the safety 
guard release lever so the blade starts 
cutting the work piece.
8. Release the on/off switch when the cut is 
complete and allow the blade to
stop rotating before raising the cutting 
head. This is required for safe operation
of the unit to prevent personal injury.

SLIDE CUT
These machines are equipped with a
sliding carriage system (Fig. 22) to assist 
with cutting wide pieces.
Loosening the sliding carriage lock
will release the carriage and allow
the cutting head to move forwards and
backwards. The saw blade is lowered into 
and through the front edge of the work-
piece and then pushed to the rear of the 
machine to complete a cut. 
1. Position the work-piece on the table and
against the fence and secure with clamp(s)
as appropriate.
2. Loosen the slide lock screw (Fig. 23).
3. Grasp the cutting handle and pull the
cutting head forward until the arbor (centre
of saw blade) is directly over and above the
front edge of the work-piece.
4. Operate the ON/OFF trigger switch and 
allow the saw blade to reach full speed.
5. Operate the safety guard release lever to 
release the cutting head.
6. Push the cutting handle all the way down 
and cut through the leading edge of the 
work-piece. 
7. Gently push the cutting handle backwards 
towards the fence completing the cut.
8. Always push the cutting head to the full
